MiniB3D module for Cerberus - where to get it ?

[semar]

Hi all,
I'm a Blitz3D user and I've read that there's a MiniB3D module for Cerberus, is it available somewhere ?
Can it be used also for HTML5 target ?

Thanks for your attention,
Sergio

Welcome. @adamredwoods is the one who can answer this.

You can get it here:

https://github.com/adamredwoods/minib3d-monkey

But Adam was going to update it soon.

 

[adamredwoods]

In progress.

Ok, give it a try. I haven't completely tested it, but seems to work for HTML5 and OSX GLFW, so far.

 

[MikeHart]

Works great on OSX 10.14.8 on GLFW and HTML5

That are great news !
A big Thanks to adamredwoods

The MiniB3D module for Cerberus works like a charm, however I can't seem to run some of the examples, in particular:
minib3d_collision_test and minib3d_mojo_bunnies
I get this in the debuglog:

..FullShader success

..FastBrightShader success

Furthermore, these commands are not accepted as overload:

SetFont(LoadImage("mojo_font.png",96,Image.XPadding))
----> Unable to find overload for SetFont(Image)

and

DrawImage(GetFont(), 100,200)
--->Unable to find overload for DrawImage(Font,int,int)

Am I missing something obvious ? I've renamed the directory to minib3d as suggested and copied it to the modules directory of Cerberus.
The animation_test, firepaint3d and pick_collision_test work fine.

Yup the SetFont() stuff changed (must be a Font class), which is fine I can fix that. The network error is odd. Is that just with the minib3d_mojo_bunnies?

 

[semar]

Hi Adam,
with mojo_bunnies I get the "Unable to find overload for SetFont(Image)" error.
Once I commented it I get the (above described) Drawimage(Font,Int,Int) error.
If I comment that also I get then:

WebGL 1.0
..WEBGL 1

..FullShader success    

..FastBrightShader success

With collision_test I don't get the SetFont or DrawImage error, but directly the network error:

..FastBrightShader success

It can't load something for some reason. Is this Windows or Linux? Which browser?

It seems that the file minib3d_logo.mtl is missing someway.
I'll investigate further..

 

[semar]

The mojo_bunnies demo does work
The file minib3d_logo.mtl was missing. I've used another file and it worked.
There's no such a logo file in the whole minib3d directory though.
The overload errors by the setFont and DrawImage command are still there.

 

[semar]

The problem resides maybe in the file monkeyutility.cxs
In the function CreateMiniB3DMonkey:TMesh()
Local MINIB3DMONKEY1$= "o minib3d_logo.obj~nmtllib minib3d_logo.mtl

By the way, was the .mtl file created with blender ? May be the texture file is missing ?

 

[adamredwoods]

Great investigation! The mtl file is a text string and loading it should be bypassed.
THe problem seems to be here:
https://github.com/adamredwoods/min...c91da3cc9c64cf332e17d46f3f/tmodelobj.cxs#L489

It's checking for a null file AFTER it loads. This makes sense (no try/catch, so it fails with an exception). I can fix that.

Thanks for finding that!

I'm glad to be of any help !

Hey, it's me, the annoying guy once again

I have a question about miniB3D: does BackBufferToTex works? I was trying to port an old 'bloom' FX I had on blitzmax, and when calling it, first I got an error on TTexture:

    Method BackBufferToTex(mipmap_no=0,frame=0)
   
        TRender.render.BackBufferToTex(Self, mipmap,frame)

    End

So I changed mipmap to mipmap_no and tried again to compile. But this time, I get an error: "Indentifier BackBufferToTex not found".
If I go to TRender, I can't find a method with that name anywhere. Am I missing something?

 

[SLotman]

Another thing: I found a small bug, which I don't know exactly how to fix.

I'm creating a mesh on the fly (trying to implement a 'trail' for moving objects) and the trail was disappearing out of nowhere. Investigating it further, I saw on TRender.RenderCamera that the 'mesh' center had a crazy value, like 100000000.

So after updating my mesh using VertexCoords, I set 'mesh.reset_bounds = true', and now it is displaying all the time as it should. It appears that VertexCoords doesn't force a 'mesh bound update'?
